God alone has knowledge of the hidden reality of the heavens and the earth; and the coming of the Hour [of Judgement] is like the twinkling of an eye, or even quicker. Surely God has full power over everything. 77 When God brought you out of your mothers wombs, you knew nothing. He gave you ears, eyes, and hearts so that perhaps you would give Him thanks. 78 Do they not see the birds controlled in the atmosphere of the sky? None holds them up except Allah. Indeed in that are signs for a people who believe. 79 Allah hath appointed for you from your houses a repose, and He hath appointed for you from the skins of the cattle houses which ye find light, on the day of your flitting and on the day of your stopping, and from their wools and their furs and their hair a furnishing and an enjoyment for a season. 80 And Allah has made for you, from that which He has created, shadows and has made for you from the mountains, shelters and has made for you garments which protect you from the heat and garments which protect you from your [enemy in] battle. Thus does He complete His favor upon you that you might submit [to Him]. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They recognize the favor of Allah; then they deny it. And most of them are disbelievers. 83
